Wetwell Level Monitoring Upgrade at Collections Pump Stations

Orange County Sanitation District is soliciting work on a wetwell level monitoring upgrade at five collection pump stations across Orange County, California, with proposals due September 1, 2026.

The scope spans two distinct work streams across five locations. At Crystal Cove, MacArthur, Main Street, and Slater pump stations, the contractor will install new level transmitters and modify existing pump station control systems to enable Operations and Maintenance staff to locally select which level measurement device controls pump operation. At Edinger Pump Station, the contractor will replace the existing bubbler system with a new bubbler panel featuring redundant instruments and an automatic blowdown feature. The project addresses aging monitoring equipment and seeks to enhance system reliability, redundancy, and operational flexibility across dispersed wastewater collection infrastructure while maintaining service continuity.

Work locations are Crystal Cove Pump Station (6925 E Coast Hwy, Newport Beach, CA 92657), MacArthur Pump Station (4219 MacArthur Blvd, Newport Beach, CA 92660), Main Street Pump Station (1499 Main St, Irvine, CA 92714), Slater Pump Station (7202 Slater Ave., Huntington Beach, CA 92647), and Edinger Pump Station (5507 Edinger Ave, Huntington Beach, CA 92649). The contractor must coordinate installations across multiple geographically dispersed active wastewater collection facilities.
